Exhaust smells really bad

[drift_raptor]

i don't know what the problem is if there is on, but i would really like to make this go away! I run a 2.5 down pipe and a 3in. strait pipe. Any advice on this would be really helpful!

it doesn't sound like you have a problem. The smell is most likely becuz you don't run a cat.

Not having a cat will definitely make it smell funny. I get the WTF look all the time from people who ride in my car.

Running too lean can cause a foul odor from the exhaust.

Other signs of a lean mixture are light grey deposits in the exhaust tip and overheated spark plugs.
See http://www.centuryperformance.com/spark2.asp for example spark plug images.

Do you have an EGT gauge? Lean will raise the EGT.

No i dont have a EGT gauge i may look into one, i just changed my spark plugs also to the OEM i had iridium POS's before made the car run like crap. They had some white powdery stuff on them but nothing really major, car runs great now. Thanks for the tips guys! My BOV is not vented properly and runs to the atmosphere for the moment so i dont think im lean on my AFR i think im running rich actually. I am going to recirc it later.
